So, it’s important to find out which games suit your gaming needs before you start playing. Learn more about the various types of online slots below.

    Three-Reel Classic Slots
    Five-Reel Video Slots
    Multi-Payline Slot Games
    3D Slots
    Progressive Jackpot Slots

    Classic slots are retro-themed slot games inspired by traditional fruit machines. They usually have three reels and a few paylines compared to today’s video slot machines. Also, classic slots may lack special features such as Wilds, Scatters and free spins. Symbols on the reels include lucky 7s, bells, bars and different types of fruits.

    The most popular slots games available at UK casinos fall under the video slot category. These are advanced online slot machines with a 5×3 layout, tens to thousands of paylines, stunning graphics and lots of bonus features with potentially big wins. Their themes are based on virtually anything you can imagine, from movies to wildlife. Modern video slots may feature Wilds, Scatters symbols, multipliers, free spins, mini-games, fixed jackpots, progressive jackpots, cascading reels, immersive soundtracks and many more special features.

    Some video slot games come with an unbelievable number of paylines. For instance, there are slot machines with more than 100,000 ways to win. These are known as Megaways slots, and they usually have more than six reels. Winning combinations are normally created by landing identical symbols on adjacent reels. Some slot games use the innovative Infinity Reels engine, which adds new reels whenever you land a winning combination. The best thing about this feature is that the cash prize increases depending on the size of the grid.

    These types of online slots benefit from three-dimensional (3D) elements. They may include life-like characters and animated symbols that make the gameplay even more interesting. Just like regular video slot games, 3D slots are inspired by all sorts of things. They can use themes based on video games, sports, movies, animals, mythology and many more. The biggest difference is that 3D casino slots feature innovative animations that create a more engaging gaming environment. They also run very well on mobile phones and tablet devices.

    Your typical online slot game will award prizes based on a paytable, but progressive jackpot slots are a bit different. Besides awarding the usual payouts, progressive slots have the potential to pay you huge cash prizes in a single spin. The jackpot amount keeps growing because each player’s bet contributes to the prize. This means that some progressive jackpot slots can have prizes worth millions of euros. The jackpot resets to a predefined amount (seed) when a lucky player wins the prize.

    Play Fair Slot Games from Respectable Software Providers

    You can only trust slot games that come from reputable game developers. We keep this in mind when reviewing slot casinos so you can find fair slots. Our casinos are powered by trusted software providers such as Microgaming, Playtech, NetENt, Quickspin, Play’n GO, Big Time Gaming and Evolution Gaming. These companies ensure fairness by creating casino slots using random number generator (RNG) software. Besides that, their games are tested by top testing agencies like eCOGRA, iTech Labs, TST, BMM Testlabs and GLI.

    Mobile Slots for Smartphones and Tablet Devices

    There is no denying that the future of online casino gaming is mobile. In fact, most UK players use smartphones and tablets to play online slots. A decent casino site will let you use any handheld device to play mobile slots from the comfort of your own home. So, you are good to go if you have an iOS or Android device with a mobile browser. Some online casinos even have mobile apps that you can download and install on your mobile device.

    Online Slot Tips

    Even though slots are primarily games of chance, you can apply some tricks to improve your gaming experience. Our experts have many years of experience, so they know some helpful tips that you can capitalise on. The following are some of the things you can do to stay longer in the game and boost your winning chances.

    Play Low House Edge Slot Games

    Online slots with a low house edge have a higher return to player rate. If the house edge is low, it means that you are likely to get most of your bets back in the long run.

    Check for Slot Volatility

    Slot games can have low, medium or high volatility. Low volatility slots offer frequent but small payouts. On the other hand, a highly volatile slot game offers sporadic wins, but you may hit a big win in a short time.

    Pick Slot Games with Lucrative Bonus Features

    Look for slots with rewarding bonus rounds and lots of special features. A slot game with a free spins feature will let you spin the reels several times for free if you activate the feature. So, you can still win some money with the current bet during the bonus round.

    Claim Casino Bonuses for Slots

    Great UK casinos will let you play slot games using a casino bonus. Thus, you should make sure that the selected casino site features bonuses for slot games. Free spin bonuses are the most common types of incentives for slot game players. Other useful promotions include daily jackpots, cashback deals, reload bonuses and weekly or monthly slot tournaments.

    Try Progressive Jackpot Slots with Huge Cash Prizes

    Progressive slots are the best option if your objective is to win huge amounts of money. Even though the RTP may be a bit low, progressive jackpot slots can offer life-changing amounts of money if you get lucky.

    Play Responsibly

    Responsible gambling is something every gambler should embrace all the time. Whether you are playing online slots or table games, you must always play responsibly. Responsible gambling entails sticking to a budget, taking breaks when necessary and seeking help if you develop an addiction.

    Contact Support if You Need Help

    Serious casino operators will do everything possible to offer the best gaming experience, including providing help if you face any issues. Our experts test the quality of customer support services by contacting the casino’s agents. In case you need help, you can always get in touch with the customer support representatives via the live chat feature, phone call or email. We expect a good slot casino to provide timely and useful answers to your problems.

    Reputable slot casino websites also have a comprehensive FAQ page with quick solutions. There, you can find answers to the most common problems you are likely to face. Some of them even have subheadings that will take you directly to the relevant category depending on what you are looking for.  You will find FAQs about registration, verification, deposits, withdrawals, bonuses, promo codes and many more. We recommended visiting the FAQ section before contacting support to see if there is an answer to the issue you are facing.
